v2.1.148

Summary

Claude Code v2.1.148 is a single-fix hotfix release, patching a regression introduced in v2.1.147 where the Bash tool returned exit code 127 on every command for some users. Released approximately 5 hours after v2.1.147.

Implications

• Release cadence thread: The rapid hotfix (5 hours) for a Bash tool regression shows the release pipeline can respond to critical breakages quickly. Exit code 127 (command not found) on every Bash call would render the agent non-functional for affected users.
• Quality signal: A regression this severe shipping in a 30+ fix release suggests the test surface for Bash tool reliability may have a gap. The fix-forward approach (new release rather than rollback) is consistent with Claude Code’s versioning pattern.
